Ear acupuncture, also known as auricular acupuncture, is a therapeutic practice that involves inserting thin needles into specific points on the ear to stimulate the body's energy flow and promote healing. It is based on the concept that the ear is a microcosm of the entire body, and stimulating certain points can address a wide range of physical, emotional, and mental issues. Common uses include pain management, stress reduction, addiction recovery, and improving overall well-being.
